Figure 1. Photomicrograph pane showing histological development of the anterior chamber angle. At F7w (A), the angle structures are absent. At F10w and F15w (B and D), the primitive anterior chamber angle was formed by densely packed cells. At F18w and beyond (E), the cells at the iridocorneal angle decreased in number and density. Between F15w and F27w (DJ), the gradual appearance of immature trabecular beams with sparse intertrabecular spaces and lined by spindle shaped trabecular meshwork cells was noted. Note the anteriorly inserted ciliary body and incompletely cleaved angle from F7w to F27w. Schlemm’s canal appeared at F21w (G). A structurally mature Schlemm’s canal and a well developed trabecular meshwork was observed at F27w (J) and beyond, and a well developed trabecular meshwork was observed at P5m (K) and in the adult eye (L). F, fetus; w, week; m, month; y, year; C, Cornea; P, postnatal. The asterisk indicates the location of Schlemm’s canal. An arrow indicates an iridocorneal angle. Double arrows indicate the trabecular meshwork. Scale bar=50 μm.
